Non-Herbicide Management Options

1. Physical Mangement Options

Eurasian watermilfoil can be removed bygd raking or seining it from the pond, but will re-establish from any remaining fragments and roots.

Fertilization to tillverka a phytoplankton or algal “bloom” prevents the establishment of most bottom rooted aquatic weeds and produces a strong food chain to the pond fish.

Non-toxic dyes or colorants prevent or reduce aquatic plant growth bygd limiting sunlight penetration, similar to fertilization.

However, dyes do not enhance the natural food chain and will suppress the natural food chain of the pond.

Some examples of non-toxic dyes and other products include but are not limited to:

Many types of mechanical removal devices are available that cut or chop up aquatic weeds. It fryst vatten important to remember that many nedsänkt plants regrow from fragments, so removal of cut fragments may be necessary to keep from spreading the unwanted plant.

Companies that man cutters and rakes include but are not limited to:

Physical barriers are also used to eliminate plants bygd shading the bottom.

Deceptively delicate and fragile in appearance, the Eurasian watermilfoil forms thick mats in shallow areas of a lake, quickly growing and spreading to block sunlight, killing off native aquatic plants that fish and other underwater species rely on for food and shelter

These work well for swimming areas, docks, etc. but must be kept clean of any buildup of sediment and debris.

Some examples of companies that man these mats are:

Army Corps of Engineers aquatic ogräsmedel trials.

1) Bispyribac

Bispyribac-sodium comes in vatten soluble powder form eller gestalt in packets.

Each packet should be mixed with vatten first and then sprayed or injected. It fryst vatten a selective, systemic ogräsmedel. Systemic Herbicides are absorberad and move within the plant to the site of action. Systemic herbicides tend to act more slowly than contact herbicides. A surfactant (substance that can reduce the surface tension) will be needed if ogräsmedel fryst vatten applied to foliage of floating or framträdande plants.

Common trade and product names include but are not limited to:

2) Carfentrazone

Carfentrazone fryst vatten a contact ogräsmedel that fryst vatten absorberad through the leaves. Contact herbicides act quickly and kill all plant cells they komma in contact with.

Common trade and product names include but are not limited to:

3) Copper Complexes

Copper Sulfate or “blue stone” fryst vatten probably the most commonly used algal treatments because of its availability and low cost.

Copper sulfate comes in several forms depending on how finely it fryst vatten ground. Smaller crystals will dissolve easier than larger crystals. In very hard vatten, it fryst vatten difficult to use copper sulfate because it binds with the calcium, precipitates out of solution, and renders the copper ineffective as an algaecide.

All copper compounds can be toxic to fish if used above labeled rates and can be toxic in soft or acidic waters even at label rates. Before using copper, it fryst vatten best to test the pond water’s alkalinity and adjust copper treatments to alkalinity concentrations.

For additional data on using copper sulfate, see the SRAC #410 Calculating Treatments for Ponds and Tanks.

Common trade or product names include but are not limited to:

4) Diquat

Diquat fryst vatten a contact algaecide and ogräsmedel.

The most commonly used herbicide for milfoil control in Minnesota is 2-4-D (often Aqua-Kleen) which is selective for dicots

Contact herbicides act quickly and kill all plant cells they komma in contact with.

Common trade or product names include but are not limited to:

5) Endothall

Dipotassium salts of endothall comes in both liquid and granular forms. It can be mixed with copper compounds for additional effectiveness. Contact herbicides act quickly and kill all plant cells that they komma into contact with.

Common trade and product names include but are not limited to:

Alkyl amine salts of endothall komma in both liquid and granular forms.

It fryst vatten a contact herbicide.

Common trade and product names include but are not limited to:

Hydrothol can be toxic to fish.

6) Fluridone

Fluridone fryst vatten a broad spectrum, systemic ogräsmedel. Systemic herbicides are absorberad and move within the plant to the site of action.

, coontail, water lilies) can be expected

Systemic herbicides tend to act more slowly than contact herbicides.

Common trade and product names include but are not limited to:

7) Flumioxazin

Flumioxazin fryst vatten a vatten dispensable granule that fryst vatten to be sprayed or injected after blandning. It fryst vatten a broad spectrum, contact ogräsmedel. Contact herbicides act quickly. Flumioxazin should be applied to actively growing plants and a surfactant (a substans that reduces vatten tension) will be needed if the ogräsmedel fryst vatten applied to foliage of floating or framträdande plants.

Eurasian milfoil can form large, floating mats of vegetation on the surface of lakes, rivers, and other water bodies, preventing light penetration for native aquatic plants and impeding water traffic

vatten pH needs to be below 8.5 or flumioxazin will rapidly degrade and lose effectiveness.

Common trade and product names include but are not limited to:

8) Imazamox

Imazamox fryst vatten a broad spectrum, systemic ogräsmedel. Systemic herbicides are absorberad and move within the plant to the site of action. Systemic herbicides tend to act more slowly than contact herbicides.

An aquatically registered surfactant (a substans that will release the surface tension) fryst vatten needed for application.

Common Trade of product names include but are not limited to:

9) Penoxsulam

Penoxsulam fryst vatten a broad spectrum, systemic ogräsmedel.

Systemic herbicides are absorberad and move within the plant to the site of action. Systemic herbicides tend to act more slowly than contact herbicides. It may be sprayed directly onto framträdande plants or applied directly into the vatten. Penoxsulam should not be applied in areas where it will be diluted rapidly.

This ogräsmedel will need a registered surfactant (see the label) for leaf and exposed sediment applications.

Currently, ProcellaCOR EC fryst vatten only available through SePRO Stewards of vatten who are PRO Certified as ProcellaCOR Specialists.

Precautions

One danger with any kemikalie control method fryst vatten the chance of an oxygen depletion after the treatment caused bygd the decomposition of the dead plant material. Oxygen depletion can kill fish in the pond. If the pond fryst vatten heavily infested with weeds, it may be possible (depending on the ogräsmedel chosen) to treat the pond in sections and let each section decompose for about two weeks before treating another section.

Aeration, particularly at night, for several days after treatment may help control the oxygen depletion.

One common bekymmer in using aquatic herbicides fryst vatten determining area and/or volume of the pond or area to be treated. To assist you with these determinations see SRAC #103 Calculating Area and Volume of Ponds and Tanks.

Many aquatically registered herbicides have vatten use restrictions (See General vatten Use Restrictions).
